The jumbo-sized Baker family are back in this sequel to the 2003 box-office hit Cheaper by the Dozen. College football coach Tom Baker (Steve Martin) and his wife, author Kate Baker (Bonnie Hunt), have decided its time they took their sizable brood of 12 children on a summer vacation, and so they pack up the cars and take the kids to Lake Winnetka for some camping. Not all the kids are happy about this, but the one who is really annoyed turns out to be Tom, who discovers his old rival Jimmy Murtaugh (Eugene Levy) is also staying near the lake. Jimmy and his trophy wife, Sarina (Carmen Electra), also have a large family of eight children, and Jimmy and Tom seem intent upon one-upping each other at every opportunity. As the tensions mount, the Baker family and the Murtaugh clan face off in a not-so-good-natured series of family games to determine which of the parents have the greater bragging rights. In addition to Steve Martin and Bonnie Hunt, the actors playing the 12 Baker children from the 2003 film return for Cheaper by the Dozen 2, including Hilary Duff, Piper Perabo, Tom Welling, and Kevin Schmidt. ~ Mark Deming, Rovi
